Method Detail

getStyleKitFamily

public java.lang.String getStyleKitFamily()

Description copied from interface: ThemeControl

The styleKitFamily is basically the default themeId, to use if the "themeId" property is not set on this control instance in the XPage source. For example, "InputField.EditBox" is used for most Edit Box controls. See Domino/xsp/nsf/themes/webstandard.theme for more examples.

The implementation may return different values depending on the configuration of the current control, for example the Button control returns a different value and looks different when it is configured as a cancel button.

Specified by:

Returns:

a non-null themeId corresponding to the configuration for this type of control in a theme file.
